CVE-2023-53187

CVE-2023-53187 pertains to the Linux kernel’s btrfs code. The vulnerability arises when a task creates a new block group that later becomes unused during the creation window. In btrfs_create_pending_block_groups(), if btrfs_mark_bg_unused() runs and moves the group out of the ‘new’ list into ‘unu...

CVE-2022-50250

CVE-2022-50250 — Linux kernel regulator core use_count leakage (boot-on) . The advisory describes a leakage where, when a regulator rdev (A) is boot-on, enabling its supply regulator (B) increments B’s use_count inside regulator_enable(rdev->supply). If B is also boot-on, it behaves as always-...

CVE-2022-50247

CVE-2022-50247 concerns a Linux kernel USB xHCI MTK driver issue: if wakeup IRQ setup fails, the shared HCD is leaked because usb_put_hcd() may not NULL the @shared_hcd before decreasing usage. The patch (referenced in the description) fixes leakage by ensuring shared_hcd is NULLed prior to decre...
